Abstract
Description
Technical Field
[0001] This utility model relates to the field of self-regulating electric heating cable installation technology, and in particular to a multi-functional wire stripper for cutting electric heating cables. Background Technology
[0002] Electric heating cables have a flat, ribbon-like structure, making them difficult to fit with traditional wire stripping tools, resulting in complex operation. Furthermore, existing tools for stripping electric heating cables are relatively limited in function, requiring the use of multiple tools (such as utility knives, scissors, and wire crimping pliers) that work together to complete the stripping operation. While some operators use simple scissors manually to strip the cables, this over-reliance on manual labor poses safety hazards, increases the risk of injury, and is inefficient, especially in cold environments.
[0003] Therefore, it is necessary to develop a multi-functional wire stripper for cutting electric heating cables to overcome the above-mentioned technical problems. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a multi-functional wire stripper for cutting electric heating cables, which effectively overcomes the defects of the prior art.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0006] A multi-functional wire stripper for cutting electric heating cables includes a wire stripper body. The wire stripper body includes a first clamp body and a second clamp body that are hinged together in the middle and symmetrically distributed. Each of the first and second clamp bodies has a handle at one end and a clamp head at the other end. The ends of the two clamp heads away from the handles have mutually cooperating cutting heads. The clamp heads of the first and second clamp bodies can be rotated to close or separate. On the side of the two clamp heads that are close to each other, there are spaced-apart outer sheath cutting components, insulation sheath cutting components, and longitudinal cutting components for longitudinally cutting the outer sheath and insulation sheath. On the side of the first and second clamp bodies that are close to each other, there is a crimping component for cooperating and crimping terminals when they are close together. The middle sections of the first and second clamp bodies overlap each other. The first or second clamp body has a locking member for locking the two together when they are closed.
[0007] Based on the above technical solution, the present invention can be further improved as follows.
[0008] Furthermore, on the sides of the two aforementioned pliers that are close to each other, there are symmetrically distributed C-shaped first notches, second notches, and third notches respectively. The aforementioned outer sheath cutting assembly is installed at the first notch of the two aforementioned pliers, the aforementioned insulating sheath cutting assembly is installed at the second notch of the two aforementioned pliers, and the aforementioned longitudinal cutting assembly is installed at the third notch of the two aforementioned pliers.
[0009] Furthermore, the outer sheath shearing assembly includes two first blades, which are respectively fixed on the same side of the first notch of the two pliers. The middle part of the edges of the two first blades that are close to each other is respectively recessed with a C-shaped first cutting edge. When the two pliers are closed, the two first cutting edges form a ring-shaped first cutting area, and the two first cutting edges are on the same plane.
[0010] Furthermore, the aforementioned insulating sheath cutting assembly includes two second blades, which are respectively fixed on the same side of the second notch of the two pliers. The middle part of the edges of the two second blades that are close to each other is respectively recessed with a C-shaped second cutting edge. When the two pliers are closed, the two second cutting edges form a ring-shaped second cutting area. The width of the second cutting area is smaller than the width of the first cutting area, and the two second cutting edges are on the same plane.
[0011] Furthermore, the aforementioned longitudinal cutting assembly includes a cutter holder and a cutter head, which are respectively fixed on the same side of the third notch of the two aforementioned clamp heads. The cutter holder has a C-shaped limiting notch on the side near the cutter head, and the cutter head has a conical third cutting edge in the middle of the side near the cutter holder. When the two aforementioned clamp heads are closed, the third cutting edge is embedded in the limiting notch.
[0012] Furthermore, the handles are connected by elastic elements.
[0013] Furthermore, the aforementioned elastic element is a spring.
[0014] Furthermore, on the side of the first clamp and the second clamp that are close to each other, an extension is provided at the position near the hinge of the two. One of the extensions has a plurality of terminal pressing blocks protruding from its end, and the other extension has a fitting groove corresponding to the terminal pressing blocks. When one end of the first clamp and the second clamp are closed, the terminal pressing blocks are embedded in the corresponding fitting grooves.
[0015] Furthermore, the aforementioned locking component includes a plate-shaped locking seat with a locking protrusion on its outer edge. The locking seat is rotatably mounted on the middle section of the first clamp body near the second clamp body via a pin. The outer edge of the middle section of the second clamp body is provided with a locking notch. After the jaws of the first and second clamp bodies are closed, the locking seat is used to rotate under the action of external force, causing the locking protrusion to extend into the locking notch and abut against the wall of the locking notch, thereby preventing the jaws from opening.
[0016] Furthermore, the edge of the aforementioned locking seat is provided with an operating part for operating its rotation.
[0017] The advantages of this utility model are: reasonable structural design, diversified functions, one tool can realize the circumferential cutting of the outer sheath of the electric heating cable, the longitudinal cutting of the insulating sheath and the circumferential cutting and terminal crimping, which is highly efficient, safe and reliable, easy to operate, and avoids carrying multiple tools during operation.

Detailed Implementation
[0028] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0029] Example
[0030] like Figure 1 , 2 As shown in Figure 4, the wire stripper includes a wire stripper body 1. The wire stripper body 1 includes a first clamping body 11 and a second clamping body 12 that are hinged together and symmetrically distributed in the middle. Each of the first clamping body 11 and the second clamping body 12 has a handle 13 at one end and a clamping head at the other end. The ends of the two clamping heads away from the handles 13 are provided with mutually cooperating cutting heads 14. The clamping heads of the first clamping body 11 and the second clamping body 12 can be rotated to close or separate. On the side of the two clamping heads that are close to each other, there are spaced-apart outer sheath cutting components 15, insulating sheath cutting components 16, and longitudinal cutting components 17 for longitudinally cutting the outer sheath and insulating sheath. On the side of the first clamping body 11 and the second clamping body 12 that are close to each other, there is a crimping component 18 for cooperating and crimping terminals when the two are close together. The middle sections of the first clamping body 11 and the second clamping body 12 overlap each other. The first clamping body 11 or the second clamping body 12 is provided with a locking member 20 for locking the two together when they are closed.
[0031] In this embodiment of the multi-functional wire stripper for cutting electric heating cables, the first clamp body 11 and the second clamp body 12 are similar in shape to traditional pliers. The first clamp body 11 and the second clamp body 12 can be opened and closed under external force at the hinge point around the terminal, so that the clamp heads of the two clamps can be closed or separated (similarly, the handles 13 can be closed or separated, wherein when the two handles 13 are closed, the clamp heads of the two clamps are also closed, and when the handles 13 are separated, the clamp heads are also separated). The clamp heads can be closed and the outer sheath cutting assembly 15 can be used to cut (circumferential cut) the outer sheath (a in the figure). The clamp heads can be closed and the insulation sheath cutting assembly 16 can be used to cut (circumferential cut) the insulation sheath (b in the figure). The clamp heads can be closed and the longitudinal cutting assembly 17 can be used to cut the outer sheath and the insulation sheath along their longitudinal direction (i.e., the length direction). The clamp heads can be closed and the heating baseband (c in the figure) can be cut, and the busbar (d in the figure) can be stripped. Finally, the internal busbar is exposed, and terminals are installed at the ends of the busbar. The terminals and busbar are then crimped together using the crimping assembly 18. The entire clamp can be locked in place by operating the locking element 20 when the clamp heads are closed, maintaining the closed position for easy storage. Alternatively, the handle 13 can be continuously applied to close the clamp under certain conditions. The overall structure is rationally designed and multifunctional. One tool can perform circumferential cutting of the outer sheath of the electric heating tape, longitudinal cutting and circumferential cutting of the insulation sheath, and terminal crimping. It is highly efficient, safe, reliable, and easy to operate, eliminating the need to carry multiple tools during operation.
[0032] Handle 13 is a plastic handle with anti-slip texture on the outer surface.
[0033] As a preferred implementation method, such as Figure 3 As shown, the two pliers heads are respectively provided with symmetrically distributed C-shaped first notches 21, second notches 22 and third notches 23 on the side of each other. The outer sheath cutting assembly 15 is installed at the first notch 21 of the two pliers heads, the insulating sheath cutting assembly 16 is installed at the second notch 22 of the two pliers heads, and the longitudinal cutting assembly 17 is installed at the third notch 23 of the two pliers heads.
[0034] In the above implementation scheme, the first notch 21, the second notch 22, and the third notch 23 are provided so that when the clamps are closed, an area for accommodating the electric heating cable is formed between the first notch 21, the second notch 22, and the third notch 23 on the two clamps. In conjunction with the outer sheath cutting assembly 15, the insulation sheath cutting assembly 16, and the longitudinal cutting assembly 17 at each notch, the operation of cutting different structural layers of the electric heating cable can be realized. The design is relatively reasonable.
[0035] As a preferred implementation method, such as Figure 6As shown, the outer sheath shearing assembly 15 includes two first blades 151. The two first blades 151 are respectively fixed on the same side of the first notch 21 of the two pliers. The middle part of the edges of the two first blades 151 that are close to each other is respectively recessed with a C-shaped first cutting edge 1511. When the two pliers are closed, the two first cutting edges 1511 form a ring-shaped first cutting area, and the two first cutting edges 1511 are in the same plane.
[0036] In the above implementation scheme, when the pliers are separated, the end of the electric heating cable is inserted and passed between the first blades 1511 of the two first blades 151. The handle 13 of the wire stripper body 1 is then closed, causing the pliers to close. The two first blades 1511 act on both sides of the electric heating cable, thus cutting off the outer sheath of the electric heating cable (if there is any uncut portion, it can be cut off using the cutting head 14). The operation is relatively convenient and quick.
[0037] It should be noted that: such as Figure 3 , 5 As shown in Figure 6, the two pliers heads can be staggered and overlapped. One first blade 151 is fixed to the side end of the corresponding pliers head by a screw passing through it. The other first blade 151 is clamped between itself and the side end of the corresponding pliers head by a first limiting block (represented by e in the figure), and is assembled to the pliers head by a screw passing through the limiting block and the first blade 151. This ensures that the two first blades 151 are in the same plane, ensuring effective cutting of the outer sheath.
[0038] As a preferred implementation method, such as Figure 7 As shown, the insulating sheath cutting assembly 16 includes two second blades 161, which are respectively fixed on the same side of the second notch 22 of the two pliers. The middle part of the edges of the two second blades 161 that are close to each other is respectively recessed with a C-shaped second cutting edge 1611. When the two pliers are closed, the two second cutting edges 1611 form a second cutting area in the shape of an annular racetrack. The width of the second cutting area is smaller than the width of the first cutting area, and the two second cutting edges 1611 are on the same plane.
[0039] In the above implementation scheme, the end of the electric heating cable after stripping the outer sheath is inserted and passed between the second blades 1611 of the two second blades 161. The handle 13 of the wire stripper body 1 is then closed, causing the pliers head to close. The two second blades 1611 act on both sides of the electric heating cable, thus cutting off the insulation sheath of the electric heating cable (if there is any uncut part, it can be cut off using the shearing head 14). The operation is relatively convenient and quick.
[0040] It should be noted that the two pliers heads can be staggered and overlapped. One of the second blades 161 is fixed to the side end of the corresponding pliers head by a screw passing through it. The other second blade 161 is clamped between itself and the side end of the corresponding pliers head by a second limiting block (indicated by f in the figure), and is assembled to the pliers head by a screw passing through the second limiting block and the second blade 161. This ensures that the two second blades 161 are in the same plane, ensuring effective cutting of the insulating sheath.
[0041] As a preferred implementation method, such as Figure 8 As shown, the longitudinal cutting assembly 17 includes a cutter holder 171 and a cutter head 172. The cutter holder 171 and the cutter head 172 are respectively fixed on the same side of the third notch 23 of the two clamp heads. The cutter holder 171 has a C-shaped limiting notch 1711 on the side near the cutter head 172. The cutter head 172 has a conical third cutting edge 1721 in the middle of the side near the cutter holder 171. When the two clamp heads are closed, the third cutting edge 1721 is embedded in the limiting notch 1711.
[0042] In the above implementation scheme, when longitudinal cutting of the outer sheath or insulating sheath is required, the heating cable is passed through the limiting notch 1711, and the handle 13 is closed, so that the tip of the third blade 1721 cuts into the outer sheath or insulating sheath of the heating cable. Then, while maintaining the closed position, the heating cable is pulled to longitudinally cut the outer sheath or insulating sheath along its length, which is very convenient. More specifically, after the outer sheath or insulating sheath is circumferentially cut, the end is inserted into and passed through the limiting notch 1711, the tip of the third blade 1721 cuts into the middle of one side of the outer sheath or insulating sheath, and then the heating base is pulled to longitudinally cut it.
[0043] It should be noted that the third cutting edge 1721 has a certain width, and the width direction is perpendicular to the length direction of the pliers body. The cutter holder 171 is assembled to the corresponding side end of the pliers head by a screw that passes through it, and the cutting tip 172 is also assembled to the corresponding side end of the pliers head by a screw that passes through it.
[0044] In this embodiment, the blades (first blade and second blade) can be replaced with other sizes and models according to usage requirements.
[0045] In this embodiment, an elastic element 131 is connected between the handles 13. When closing the handles 13, the elastic element 131 needs to be compressed. After the operation is completed, the external force is removed, and the handles 13 can automatically separate under the elastic force of the elastic element 131, which means that the pliers heads automatically separate, making it convenient for subsequent operations.
[0046] In this embodiment, the elastic element 131 can be a spring.
[0047] More specifically, on the side of the first clamp 11 and the second clamp 12 that are close to each other, an extension protrudes from near their hinge point. One of the extensions has multiple terminal clamping blocks 181 protruding from its end, and the other extension has a corresponding fitting groove at its end. When one end of the first clamp 11 and the second clamp 12 is closed, the terminal clamping blocks 181 are inserted into the corresponding fitting grooves. By placing the terminal inserted into the busbar end into the fitting groove and applying pressure by gripping the handle 13, the terminal clamping blocks 181 are inserted into the fitting groove, thus crimping the terminal. This ingenious design facilitates terminal assembly.
[0048] In this embodiment, the middle sections of the first clamp body 11 and the second clamp body 12 overlap each other. A locking member 20 is provided in the middle section of either the first clamp body 11 or the second clamp body 12. The locking member 20 is used to lock the two clamp bodies 11 or 12 when their jaws are closed. After the handle 13 is closed, the locking member 20 can lock the two clamp bodies 11 or 12, keeping them in a closed position.
[0049] In a preferred embodiment, the locking member 20 includes a plate-shaped locking seat 201. The outer edge of the locking seat 201 is provided with a locking protrusion 202. The locking seat 201 is rotatably mounted on the middle section of the first clamping body 11 near the side of the second clamping body 12 via a pin. The outer edge of the middle section of the second clamping body 12 is provided with a locking notch. After the jaws of the first clamping body 11 and the second clamping body 12 are closed, the locking seat 201 is used to rotate under the action of external force, so that the locking protrusion 202 extends into the locking notch and abuts against the wall of the locking notch, thereby preventing the jaws from opening.
[0050] In the above implementation, after the pliers are closed, rotating the locking seat 201 will cause the locking protrusion 202 to rotate until its end abuts against the wall of the locking notch. This will prevent the pliers from shifting outward and prevent the pliers from separating.
[0051] In this embodiment, a protruding operating part is provided at the outer edge of the locking seat 201. Applying external force to the operating part can drive the locking seat 201 to rotate.
[0052] In this embodiment, the locking seat 201 is rotatably assembled with the corresponding clamp body middle section via a locking pin at the center.
